This sturdy nest box from Duvo + has a round entrance and is very suitable for various garden birds. At the back there is 1 lockable opening. The roof is galvanized so that the nest box lasts a long time. Your garden birds can quietly build their nest in this nest box or take a breath on the perch. Hang the nest box at about 2 meters high so that cats cannot reach it. Make sure that the nest box hangs in a quiet place where the birds are not or little disturbed.
